Specification of Letters Patent.

Application filed April 19, 1916. Serial No. 92,139.

To all whom it may concern:

Be it known that I, OSCAR L. VANCE, a citizen of the United States, anda resident of Decatur, in the county of Adams and State of Indiana, haveinvented a certain new and useful Improvement in Locks, of which thefollowing is a specification.

My present invention relates generally to looks and more particularly toa lock of the permutation type, adapted for general application in theuses to which looks are adapted, and particularly useful for locking theoperating parts of an automobile in either operative or inoperativecon-.

dition.

The preferred constructlon of my lnvention, applicable as-it is tovarious uses as hereinafter shown, will be better understood byreference to the following description, in connection with theaccompanying drawings forming a part of this specification, and in whichFigure 1 is a perspective view of my improved lock with connections forusing the same in an automobile. Fig. 2 is a vertical longitudinalsection through the. lock. Fig.

3 1s a cross, section taken substantially on line 3-3 of Fig. 2. Fig. 4is a perspective view illustrating certain parts of the lock in detachedrelation. Fig. 5 is a view partly in elevation and partly in section,illustrat- ,ing a modified mounting for the lock in connection with thedash of an automobile. Fig. 6 is a sectional view illustratingapplication of the look as a mortise lock for doors, etc.. Fig.7 is adetail perspective view of the inner end of the shaft, constructed foruse as in Fig. 6. Fig. 8 is a view, partly in elevation and partlybroken away and in section, illustrating its use as an outside doorlock, and Fig. 9 is a view similar to Fig. 'Yfor use in connection withFig. 8.

Referring now to these figures, the lock as' proposed by my invention,and in each instance of its use, includes a cylindrical shaft 10 havinglateral extensions 11 projecting in diametrically opposite directionsfrom its outer end and forming a handle,

' and provided with an inner reduced portion 12 forming an annularshoulder 13 intermediate itsends and against which shoulder abuts awasher 14 mounted on the reduced portion 12. The shaft 10 is alsoprovided with a longitudinally extending key slot 15 projectingsubstantially from its handle at the outer end thereof, to a pointadacent the inner end, for the reception of a key 16 having an outerangular projection 17 forming a finger-piece adjacent the handle 11 ofthe shaft, and having an inner angular locking end 18. This key 16 isalso provided at a point intermediate its ends with serrations or teeth19 forming notches between them in which are seated the inner bevelededges 20, of permutation disks 21, 22, and 23, surrounding the centralopening 241 of said disks which receive the reduced portion 12 of theshaft 10.

The disks 21, 22, and 23 are each also provided with a slot 25 at onepoint in its inner beveled edge 20, so that when the slots of theseveral disks are alined with the key 16, the latter may be movedlengthwise in the shaft groove 15, to and away from locked position.

lhe reduced portion 12 of the shaft extends through the central openingof the lock plate 26 having a hub portion 27 rovided at one face withrecesses 28 an 29 at an angle of 90 with respect to one another, andeach of which is adapted for the reception of the inner angular lockingend 18 of the key 16, it being noted that the several permutation disks21, 22, and 23, before mentioned, are of progressively increasingdiameter and arranged between the 'lock plate 26 and the washer 14, soas to maintain the series of disks in position for ready adjustment inuse. Each of the said disks is provided in its rear face with slots 30diametrically opposite one another, and for the reception of bentextensions 31 of substantially concavo-convex spring plates inwardly inthe direction of itslength and v in order to move its inner locking end18 out of engagement with the recess 28 or the recess 29, and thus freethe shaft 10 for rotation by manipulation of the handle 11, to insert orwithdraw a locking bolt of a door or other structure, or open or close avalve and the like through suitable connections for this purpose.

As used in connection with a mortise door lock, as seen in Figs. 6 and7, the inner end of the shaft 10 is provided with an angular extension33 pivotally connected to one end of anarcuate bolt 34, so that rotationof the shaft 10 in opposite directions, serves to insert the bolt withinand withdraw the same. from its keeper 35, dependent upon the directionof such rotation.

As shown in Figs. 8 and, 9, in connection with an ordinary outside lock,the inner end of the shaft 10 may be provided with an angular extension36, directly movable upon rotation of the shaft into and out of itskeeper 37 As shown in Figs. 1 and, 2, however, the shaft 10, adapted inthis instance, for the control of a fuel .valve 38 within a fuel pipe39, is connected to the valve by means of a flexible shaft (not shown)incased within a flexible casing 40, so that, upon leaving theautomobile for any length of time, the operator may close and lock thevalve 38 and thus prevent unwarranted use or manipulation of the carduring his absence therefrom. In the latter instance, the inner end ofthe shaft 10 may also extend through a casing rear plate 43 of thecasing, whereby to form a bearing for the shaft and eliminatelongitudinal movement and rattling thereof, the plate 43 just mentionedbeing for this purpose in two parts, as seen in Fig. 1.

The casing 41 may be secured through an opening in the dash, indicatedin dotted lines at 44 in Fig. 2, or may be extended within an angulartubular support 45 in turn attached to the dash 46, as shown in Fig. 5.In either instance, the casing 41 may have a pair of internal springcontact fingers 47 and 48 as most plainly seen in Fig. 3, the inner freeends of which are in movable contact with a portion of the inner surfaceof the shaft 10, and the latter may, at this point, be provided with aninsulated surface 49 in which is embedded a contact plate 50. Theignition wires 51 and 52, as seen in Fig. 1, are led into the casing 41and respectively connected to the contact fingers 47 and 48, so that,when the shaft 10 is turned and looking extension 18 of key 16 engagedwithin lock plate recess 28, as shown in Fig. 3, the ignition circuitwill be completed, while,

when the shaft is turned to engage and lock' extension 18 within recess29, the contact plate 50 will be moved away from the contact finger 48and the circuit thus broken.

Rotativemovements of the shaft 10 are limited to the movement of thelocking extension 18 between pins 53 and 54 projecting inwardly from thehub portion 27 of lock plate 26, so that, in the event of the use abovedescribed, interference of the extension 18 with the contact fingers 47and 48 is prevented.

It is obvious, therefore, that a look as constructed in accordance withmy invention, is simple, comparatively inexpensive, strong,

and durable, viewed in the light of other locks of the type, and is, inaddition, capable of application to a great variety of uses inconnection with which locks of this type are generally put, and arrangedand adapted to be used in connection With various devices slot andhaving an angular finger piece adjacent the handle of the shaft, and aninner angular locking end for engagement within the locking recesses ofthe lock plate, said key having serrations intermediate its ends formingnotches therebetween, a series of permutation disks surrounding theshaft and disposed between the said lock plate and the said washer, eachof said disks having a beveled edge surrounding its central openingreceiving the shaft to interfit one of the notches of the locking keyand having a slot in its said edge through which the key may be moved inthe direction of its length when alined therewith.
